Cossatot River Bridge Improvements

The Cossatot River at Ed Banks Crossing design involved the renovation of a low water bridge on a National Wild and Scenic River.  The bridge design features are cast-in-place piers and precast concrete bridge decking.  The bridge functions as a low water bridge during high flow events.  PMI completed HEC-RAS modeling of the Cossatot River in the area of the crossing and applied for applicable regulatory permits.  The bridge was constructed in July-October 2017.  PMI received an ACEC Arkansas Engineering Excellence Award for this project in 2018.
